.a mamn filed April 16, 1924. Serial in. 706,832.

To all wkomz'tmag concern: I Be it known that I, 'PETER SWARTZEN- 'rnupnn, a citizen of the United States, r'esiding at Saratoga Springs, in the county of Saratoga and State of New York, have invented an Improvement in Oil Burners, of

- for heating purposes. Heretofore in burners of this type, so far as I am aware. difiiculties have been experienced through carbon deposits dueto incomplete combustion making it necessary to frequently clean the burner to maintain'it in operative condition. Burners of this type, as heretofore constructed, have also been objectionable due to the noisy operation thereof. The object of my present invention is to overcome these difliculties- In carrying out the invention my improved burner is so constructed as to control the extent to which the fuel is pre-heated,

to evenly distribute the fuel, and to regulate the air supply in such a manner that through these combined features the combustion of the fuel is complete for allpractical purposes, the'construction furthermore being such that no combustion takes place in the supply pipes whereby any collection of carbon or other deposits therein is entirely eliminated. In carrying out the invention the burner made in accordance therewith comprises a hollow body member having a distributing trough at one end thereof and containing supplv devices for feeding the fuel to the distributing trough. and a cap adiustable to position for controlling the supply of air which passes aroundthe supply devices through the body member and is OFFICE.

made cylindrical and of any suitable metal. 7

This body 'member is of relatively hea construction. The. cylindrical walls of the body member are designated by- 11 and at one end thereof, preferably'the upper or outer end, the same is provided with an internal flange 12 having a circular distributmg trough or channel 18 in the outer face thereof. As will be understood this construct1on of the body member provides a chamber 14 within the same and also at the flanged end thereof a discharge passage or port 15 for the air supply, as hereinafter more particularly described.

The devices for supplying the fuel to the burner consist of a series of distribution p 1pes for conveying the fuel to spaced posltlons in the base of the trough or channel 13. 4s illustrated, it will be seen that in carrying out the invention these devices may include a six way connection 16 to which corresponding ends of supply pipes 17 18, 19 and 20 are connected, while the opposite ends of these pipes are secured in the corresponding ends of elbows 21, 22, 23 and 24 and the supply pipes 25, 26, 27 and 28 which at corresponding ends are connected at the other end of the said elbows while at the opposite ends these last named supply pipes are fixed in tapped openings provided there for in the internal flange 12. The tapped openings in this flange in which these ends of the supply pipes 25, 26, 27 and 28 are connected are carried through the flange 12 and are preferably of substantially the same diameter as the interior diameter of these supply pipes as indicated at 29. 30, 31 and 32 respectively. The fifth opening or inlet to the six way connection 16 is fitted with a supply pipe 33 which by an elbow 34 as illustrated is connected by a pipe 35 to any suitable source of the oil or other fluid p y- The fuel supply devices as hereinbefore described are so designed that the six way connection assumes a central position within the body member and the pipes leading therefrom to the openings to the trough all lie entirely within the body member. The sixth opening in the six way connection is fitted with a standard or rod 36 which, as will be understood is solid and extends outwardly from the six way connection to the passage 15 to a point appreciably outside of the discharge end of the passage. The

be maintained in any position to which it may be adjusted by a nut 39* or otherwise.

drawing the outer or upper wall of the body member by virtue of the trough 13 terminates in a flange 40 and as is illustrated in.

Fig. 2 of the drawing the outer'or'upper end of the internal flange 12 terminates in a flange 41. This flange 41 i concentric with flange 40 and terminates'n a plane which is appreciably spaced from the plane. 5 in which the upper face of the flange 40;" lies. The bell-shaped cap 38 is of such a" diameter as to have its edge adapted to ex tend over the outer face ofthe flange 41 providing an annular passage 42 between the same for the passage ofthe air to the trou h as the same is deflected downwardly by t e bell-shaped cap as will be apparent. The area of this annular port is adjustable depending upon the position in which-the said bell-shaped cap is placed so as may be necessary to admit a larger or a smaller quantity of air to the trough depending upon the quantity of fuel which is supplied thereto which in turn is dependent upon the heat desired to be produced by the burner, it-

being understood, of course, that the greater the heat desired the larger the quantity of fuel that must be supplied and consequently the larger the quantity of air necessary for the complete combustion ofthe fuel.

In the operation of the hereinbefore 'described burner the same is preferably set in a vertical position as illustrated in Fig. .2 of the drawing. The supply of the fuel is regulated by the head thereof and a control cock or valve through which the fuel is conveyed to the supply pipe 35. The fuel then passes to a six way connection 16 within the body of the burner and is distributed by the four way supply-pipes to the orifices or openings leading to the bottom of the trough where the fuel is evenly distributed, vapor- .ized, mixed with the necessary quantity of air and ignited to. burn preferably substantially on a line extending between the outer edge of the bell-shaped cap 38 and the inner edge of the flange 40. It will be noted that in this operation there is a comparatively small pre-heating effect of the fuel due to the self-induced draft or passage of air through the body of the burner, which air during its passage through the body of the burner necessarily envelops the supply pipes for the fuel lying within the bodv of the burner and that the entire distribution of the fuel and its vaporization a nd admixture with the air takes place within the trough 13 from which the fuel mixture is emitted and burned so that as hereinbefore stated there is no opportunity for carbon or other deposits within the fuel supplypipes and the air supply may be so regulated that the combustion is sufliciently complete to eliminate carbon deposits in the trough itself.

It will also be understood that while I As clearly-seen in Figs. 1 and 2 of the have herein shown and described a burner structure in which four distributor pipes are employed there is no reason for limiting the invention to this particular number asany convenient or necessary number may be emthe bell shaped cap member 38 may be con structed of varying diameters relatively to w the trough 13in order to meet various conditions in operating the burner when in actual use. fFurthermore, 1n carrying out;

simply composed of bent pipe members or the, invention the pipe connections leading from the SIX way head may be integral structures; that is to say these members may be I their equivalents without employing the elbows, as hereinbefore specifically described,

and that in some instances without 'de arting from the nature of the Invention an for convenience in assembling the parts of the burner the internal flange having the trough therein may be made separately and so formed as to rest upon or-be connected to the body member in any suitable manner.
